DSG-005 Series Solenoid Operated Directional Valves
The DSG-005 Series is a compact “Mini-series” solenoid operated directional valve developed by YUKEN (Yuken Kogyo Co., Ltd.), designed for space-saving hydraulic applications while maintaining high performance and reliability.
Core Features
-
Compact Design: Significantly smaller than the DSG-01 series, enabling substantial space savings in hydraulic systems
-
High Performance: Maximum operating pressure of 25 MPa (3,630 PSI) and maximum flow rate of 15 L/min (3.96 U.S.GPM)
-
Wet Armature Solenoid: Provides longer service life, reduced noise levels, and improved durability compared to dry armature designs
-
Energy Efficient: Optimized internal design minimizes pressure loss, contributing to system energy savings
-
Versatile Electrical Options: Available with flying lead wire type or DIN plug-in connector type (IP65 protection with dust cover)
-
Universal Electromagnet: 50/60 Hz AC compatibility; DC models feature polarity-independent wiring for easy installation and maintenance
-
Multiple Spool Configurations: Two-position (2/2, 2/3, 2/4 way) and three-position (3/4 way) models with spring-centered or spring-offset spool alignment
